10 damage to the rolling stock. v

- -I-t isthe 'object' of our inventionto provide simple andefiective means for preventing the access of the packing to the brass, thus preventing waste grabs with theirres'ultant damage.

In the accompanying drawing, which illustrates' two constructions embodying cur invention, Figure 1 is an endview of a railway journal box, partly-in section and'partly in elevation, to which the preferred form of our device is applied; Figure 2 is a side view of one of the waste guards shown in Figure 1; Figure 3 is a side view showing a modified form of waste guard; Figure 4 is a section taken on the line 44 of Figure 2; and Figure 5 is a section taken on the line 5-5 of Figure 3.

Referring first to Figure 1, 1 indicates a railway journal box provided with lugs 2. Situated in the journal box is an axle 3 having a flange 4. Bearing on the axle is a brass 5 and interposed between the brass and the top of the box is a wedge 6. All of these parts are of the usual constructions.

Positioned at each side of the axle is a guard, the preferred form of which is shown in detail Each of the guards is formed of a metal plate 7 of a length equal to the length of the bearing portion of the axle to which it is to be applied and of a width somewhat greater than the distance between the box wall and the '40 bearing surface of the axle when the latter is at its extreme distance from the former, as shown in dotted lines at the left hand side of Figure 1. Intermediate of its length, the plate is provided with a recess 8 to accommodate the box .45 lug 2. One edge of the plate is turned over and projects downwardly to provide a contact face 9 to engage the bearing face of the axle. The bend in the plate forms a tubular part 10 somewhat shorter than the plate. In this tubular part is secured, by soldering or otherwise, the central portion of a spring rod 11, the ends of which are bent so as to extend across each other, as best shown in Figure 2, and are adapted to bear on the Wall of the journal box to force the contact face 9 against the axle. The lower edge of the contact face 9 is bent into a tube 12 sur rounding 'a reinforced bar 13; The forward end of this bar is provided with an inverted U-sha'ped bend 14 to extend around theflange 4 of the axle and terminates in a loop 14 forming a finger piece to enable the guard to be forced awayfr'om the axle to avoid the flange when it'is removed;

In Figures 3 and5 v've have shown a slightly modified form of the guard in which'abend16 at the'upper edge of the 'plateforms the contact face-for engaging the axle. This bend receives the reinforcing rod 13." At the center of the device the material of the plate extends upward- 1y from the bend to provide a support'l'lto which a leaf spring 18 is secured by means of a'rivet- 19. 'I-his support'is provided with aflange-- 20 to prevent rotation of the spring on the rivet. At each sideof the support the material of the plate is bent around the reinforcing rod 13, as shown at 21, and is preferably soldered or brazed thereto.

The guards are positioned in the axle bar, as shown in Figure 1, one guard being situated at each side of the axle, the lower edge of plate 7 being in contact with the side wall of the box and acting as a fulcrum on which the guard swings when the axle moves laterally with relation to the box, and the bearing face being held in contact with the periphery of the axle by the action of the spring. When the axle moves to its extreme lateral position in the box, as indicated by the dotted circle D, the guard at one side wall will be swung up into approximately a vertical position while the guard at the other side will assume an approximately horizontal position, indicated by the broken line C, its contact face traveling along the arc B. When the axle returns to normal position, it will swing on the corher A of the brass as a pivot so that the periphery of the axle at its line of contact with the guard, moves in the direction indicated by the arrow in Figure 1 and the guard is lifted to its normal position without being subjected to pressure in the direction of the width of the plate which would deform it and render the device inoperative.

It will be seen that our device provides effective shielding means operative in all relative positions of the axle and box to prevent the waste 22 from entering between the axle and the brass to form waste grabs. Further, our device may be inserted or removed with all the parts of the bearing in position and the lubricating packing in place.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent of the United States is:

1. In a device of the class described, the combination of a journal box and axle, of a brass in said box bearing on the upper part of said axle, the lower part of said box forming a chamber containing oil retaining packing, a pair of packing guards positioned in said box between the axle and the box wall, each of said guards comprising a plate extending in a diagonal direction between the axle and box wall and having a free edge in contact with the latter, a reinforcing rod at the other edge of said plate and extended to form a handle, and a spring carried by the plate andcontacting with the wall to hold the plate against the axle.

2. In a device of the class described, the combination with a journal box and axle, of a brass in said box bearing on the upper part of the axle, the lower part of the box forming a chamber containing oil retaining packing, and a packing guard positioned in the box; said guard comprising an imperforate plate contacting with one side of the box but unattached thereto, said plate being upwardly and inwardly inclined and bearing against the axle above its center, and spring means interposed between the plate and the side of the box for yieldingly maintaining the former in contact with the axle in its shifting lateral positions.

3. In a device of the classdescribed, the combination with a journal box and axle, of a brass in said box bearing on the upper part of the axle, the lower part of the box forming a chamber containing oil retaining packing, and a floating packing guard positioned in the box; said guard comprising an imperforate plate extending between the side of the box and the axle and contacting with the latter above its center, and a spring attached to the upper part of the plate and bearing against the side of the box above the line of contact of the box and plate, whereby the guard compensates for the lateral movement of the axle in the box and maintains a seal between the axle and the box in any relative position which said parts may assume.

4. In a device of the class described, the combination with a journal box and axle, of a brass in said box bearing on the upper part of said axle, the lower part of the box forming a chamber containing oil retaining packing, and a floating guard interposed between the packing and the brass, said guard comprising a plate and a spring member carried thereby, the lower edge of the plate and the spring member bearing against the side of the journal box, the plate bearing against the axle above the center of the latter, said guard being insertable in the box after the packing is placed therein.

5. In a device of the class described, the combination with a journal box and axle, of a brassin said box bearing on the upper part of said axle, the lower part of the box forming a chamber containing oil retaining packing, a floating guard in,- terposed between the packing and the brass, said guard comprising a plate having a reinforcing rod adjacent its upper edge and bearing on the axle above the center of the latter, the lower edge of the plate bearing against the side of the journal box and being recessed to accommodate a box lug, and a spring member interposed between the plate and the side of the journal box to maintain contact between the plate and the axle.
